Answer:

The reaction is not in equilibrium and it proceed in reverse direction to reach the equilibruim condition

Explanation:

We have

H₂(g) + x₂(g)  ⇆  2HX (g)

Kc = 2.4 x 10 ⁻³ at 25°C

K_c = \frac{[HX]^2}{[H_2][X_2]}

Now we have 3L reactor and the number of mole of species are 0.150 mole H₂, 0.150 mole X₂ and 0.600 mole HX

Therefore,

[H_2] = \frac{0.150}{3} \\= 0.05M

[X_2] = \frac{0.150}{3} \\= 0.05M

[HX] = \frac{0.600}{3} \\= 0.2M

Therefore,

Q_c = \frac{[HX]^2}{[H_2][X_2]}

Q_c = \frac{[0.200]^2}{[0.05][0.05]}\\\\=16

Now, we calculate the free energy change for the reaction

ΔrG = RT In Q/K

= (8.314) \times (298) \times In (\frac{16}{2.4\times 10^-^3} )\\\\=+21814.7 J/mol

As free energy is +ve so the reaction is not in equilibruim and proceed in reverse reaction to reach tje equilibruim condition

Boron carbonate decomposes into boron oxide and carbon dioxide. How many moles of CO2
Paul [167]
<h3>Answer:</h3>

15 moles

<h3>Explanation:</h3>

The decomposition of boron carbonate is given by the equation;

B₂(CO₃)₃(s) → B₂O₃(s) + 3CO₂(g)

Moles of boron carbonate decomposed is 5.0 mol

To find the moles of CO₂ produced we are going to use the mole ratio.

Mole ratio of B₂(CO₃)₃ to CO₂ is 1 : 3

Therefore;

Moles of CO₂ = Moles of B₂(CO₃)₃ × 3

                      = 15 mol

Therefore, 15 moles of CO₂ will be produced

HELP ME PLEASE I NEED HELP SO BADLY
crimeas [40]

State the given:

Moles of Sulfur = 5 moles

Molar mass of Sulfur = 32.06g/mol

Look through the formulas:

Moles = Mass/Molar Mass

Rearrange the equation:

Mass = Moles x Molar mass

Plug in your given:

5 moles Sulfur   x   <u>32.06g</u>

                                 1 mol

<u>= 160.3g of Sulfur</u>
